Some of these programs apparently exist for Windows here:

You can create it directly with a good image manipulation program and
Emacs, but the resulting image won't look very nice because reducing the
color palette isn't as good as using the ppmquant program...  If you
want to try anyway, follow these steps:

Take a 48x48 PNG image.  In your favorite image manipulation program,
modify the PNG so that it contains 12 colors or less; the resulting
image must be smaller than 740 bytes (otherwise your header would be too
long).  In The Gimp, you can do it with Image > Mode > Indexed.  (Maybe
there's a way to do quantization as well?)

Once you have a small enough PNG image, open it in Emacs using
`find-file-literally', select the whole buffer (`C-x h'), and call
`base64-encode-region'.  And the result is your Face header.  Be
careful, it must be less than 998 characters with the "Face: " put in
front, and the lines mustn't exceed 79 chars.  The detailed specs are at
<URL:http://quimby.gnus.org/circus/face/>.

Another alternative would be to upload your image somewhere, post the
URL here and ask someone with access to a GNU system to create the
header for you...

Cheers,
